Background:

Depression is a prevalent global mental health issue.
Effective detection methods for mental health conditions are crucial.
Human-machine interaction offers novel approaches to mental health assessment.

Purpose of the Study:

To investigate the use of virtual avatar communication and eye tracking for depression symptom detection.
To analyze the influence of interviewer type and conversation topic on eye gaze patterns.
To compare eye gaze patterns between individuals with and without depression symptoms.

Main Methods:

Recruited 27 participants (15 control, 12 depression symptoms group).
Recorded participants' gaze patterns using an eye tracking device.
Participants interacted with both virtual avatars and human interviewers discussing neutral topics.

Main Results:

Significant differences in eye movements were observed between the control and depression symptoms groups.
Individuals with depression symptoms exhibited larger gaze distribution during neutral conversation topics.
Eye gaze patterns varied based on interviewer type (virtual avatar vs. human).

Conclusions:

Eye tracking combined with virtual avatar interaction shows potential for identifying depression symptoms.
Gaze patterns during neutral conversations are a key differentiator between individuals with and without depression.
This technology could offer a non-invasive tool for mental health screening.
